Answer 1

Answer:

${x}^{7} - 4 {x}^{5} + 2 {x}^{4} + 4 {x}^{3} - 10$

Step-by-step explanation:

To write a polynomial in descending order means writing the polynomial in decreasing powers of x.

The given polynomial expresion is

$- 4 {x}^{5} + 4 {x}^{3} + {x}^{7} - 10 + 2 {x}^{4}$

We start from the term with the highest degree and end with term with the least degree.

${x}^{7} - 4 {x}^{5} + 2 {x}^{4} + 4 {x}^{3} - 10$

Therefore the given polynomial written in descending order is

${x}^{7} - 4 {x}^{5} + 2 {x}^{4} + 4 {x}^{3} - 10$
